Hi, i'm on OS 1.10, i have the same issue one time when i forgot to remove the usb stick connect to usb to device port after shutdown.
I remove it, since no problem.
The Os updater wasn't on the usb stick when it failed, just some library files.
So if you have your usb stick connect, remove it.

Ahhh, ok then, yes I had left the USB updater stick in the port. Out of about maybe 20 boots only two fails. Hope this fixes it.

Thank you, Joel!!!

You're Welcome 😉

Apparently that's not the fix for me after all. Booted up with no USB stick in the port, same thing... Screen lights but frozen, no front panel illumination... Is this a known issue Mr Bad Mister?

Yes, yes! This has happened to me as well, twice, - boots up with no front panel lighting, no sound, un-responsive to button pushes or touch screen but screen appears to look normal. I rebooted immediately after both times and all was fine.

Unfortunately I can't provide any clarity or info on the two variable listed by other peeps here because 1) I updated firmware immediately upon receiving Montage, so I do not know if it is from firmware update or not. I've had Montage for little over a week or so. 2) I don't recall if I had the USB drive plugged in or not.

Ok, thanks guys 😀 sooooo:

Issue: confirmed to exist (by multiple users)

Resolution: said issue to be publicly RECOGNIZED by Yamaha, and resolved in a timely manner

Exactly the same happened to me - I opened another thread without seeing this one.
My memory stick was in at the time so I'll remove it and see if it happens again

hmm troubling... you buy a flagship and its a crapshoot to see if she ignites on first boot

but when she does...

Happened to me once, the exact same thing. I don't turn off the system with the rear switch either, I cut the power using a remote power switch to my whole rig.

I have not had that problem as you guys, I leave My Samsung T3 Series 500GB External Solid State Drive plug in the usb port and use the switch on the back to turn off/on the Montage.
maybe an issue with the USB drive incompatible that caused a corruption of OS Firmware update of the montage let hope it not the montage itself.

Maybe if you get a USB that on the compatible list YAMAHA provided and go through the same procedure of re-updating the Montage OS firmware 1.10 this may resolve the issue.

If the Montage is so picky about a USB drive that data would become corrupted...

No, I don't see that being the issue. If it were, I think that Bad Mister might have offered this solution.

Yes, I would like to see a fix. In that Bad Mister has not contributed to this thread, I think they are still puzzling that fix out.

I just had the same thing happen to me: touchscreen was fine, but no lights on anything and no sound when I played the keys. Running the latest version of the firmware, 1.10.6. The machine came up fine when I rebooted it.

I don't see any 1.10.6 version on the Yamaha support site although they might not report it until it reaches 1.20 etc.

If I remember correctly, they only list 1.10 on the support site. But my Montage (Utility -- Settings -- System) shows it as 1.10.6.
